A MAN accused of raping his 12-year-old stepdaughter has claimed he could not have committed the crime because his penis is too large.

The unidentified defendant, 49, reportedly even asked a court magistrate if he could show her it in a bid to prove it's size.

According to the New Zimbabwe paper, the stepdad had taken the youngster to a nearby mountain to find wood to be used for fencing.

But while alone, he allegedly told her to remove her clothes before raping her.

The attack occurred sometime in April this year near the family's home in Gonyora village, in Bikita.

The abuse allegedly continued until the following month when the girl told her mum what had occurred.

According to the paper, he pleaded with magistrate Dambudzo Malunga to take a look at his genitals, claiming its abnormal size would exonerate him.

However, the magistrate ignored his suggestion and remanded him in custody for a continuation of trial.
